The graph below shows the number of houses sold over x days. what is the average rate of change from day 2 to day 10? -4/3 -3/4 6 8

Average rate of change =

Step-by-step explanation:

Average rate of change in houses sold is actually the slope between two points.

Lets say that the slope = m

Then m =

Here we have houses sold for day we can write it as and houses sold for day we can write it in coordinate form as tex](x_1,y_1)=(10,2)[/tex]

Plugging the values :

m = = =  

Reducing the fraction to its simplest form by dividing both numerator and denominator with 2.

=

So the average rate of change in the selling of houses from day to day is

30
